Instrumentation in Red Hill Valley Parkway Providing Data for Long Term Pavement Management

Abstract

•Collected data from instrumentation shows that the RHVP pavement is perpetual and should not develop fatigue or rutting distresses in 50 year design period •Measured tensile strain at bottom of RBM is less than 70µε •Calculated compressive strain at top of subgrade is less than 200µε. However, rutting due to subgrade deformation is considered to be the control distress. •The perpetual pavement on the RHVP should require only two resurfacings in 50 years compared to two resurfacing and a major rehabilitation that the Linc will require. •Discounted cost of maintenance and rehabilitation for RHVP is anticipated to be 2.5 times less than the Linc
